Orbital velocity is the velocity given to the body to keep it in orbit. This velocity is usually given to the artificial satellite so that it revolves round any particular planet of mass (M) at a distance from the planet center of R.  The formula is given by:

V_"orbit" = sqrt((G*M)/R)

Where:-

* G = gravitational constant,
* M = the mass of the body at center,
* R = radius of orbit.

Note: This formula only applies when one of the bodies (e.g. the satellite) has relatively negligible mass compared to the other body (e.g. the planet).
